1. Project Overview and Objectives

   TGS is undertaking the Peninsular Malaysia 3D Mega Merge Stage 4 Reprocessing project to expand its multi-client seismic coverage in the Malay basin. The primary objective is to reprocess approximately 16,000 square kilometres of legacy 3D seismic data to enhance subsurface clarity and create a consistent, basin-wide view. This initiative supports the basin's ongoing exploration renaissance by providing a unified dataset that enables faster exploration insights for operators through the application of uniform technology and workflows across all project stages.

2. Strategic Importance and Market Context

   The project is strategically timed to support upcoming opportunities in the Malaysia Bid Round (MBR), an annual licensing round hosted by Malaysia Petroleum Management and Petronas. The MBR offers a variety of investment opportunities, including exploration blocks, discovered resources, mature assets, and technical studies, allowing investors to expand their energy portfolios. By extending the regional dataset to cover key exploration blocks relevant to the MBR, the project builds on earlier phases to bolster growing exploration interest, a trend validated by recent discoveries within the basin.

3. Technical Methodology and Data Enhancement

   In collaboration with its joint venture and processing partner, DUG, TGS employs advanced seismic processing techniques to improve data quality. These methods include broadband processing, full-waveform inversion, and pre-stack depth migration, which collectively enhance the imaging of deeper geological targets and complex structural settings. This technical approach ensures that the reprocessed data offers superior clarity and is tailored to meet the demands of modern exploration.

4. Benefits and Value Proposition for Operators

   The reprocessed dataset provides significant advantages for energy companies, including a ready-to-license resource that facilitates rapid screening, lead identification, and more confident prospect evaluation. By offering a continuous, basin-wide view achieved across all Mega Merge stages, operators can bypass the lead time typically associated with new seismic data acquisition. The multi-client model further enhances accessibility by providing a cost-effective entry point for companies preparing for near-term licensing, while ensuring continuity with prior project deliverables. This integrated result supports comprehensive basin-wide analysis, consistent attribute interpretation, and streamlined prospect maturation, enabling operators to transition from initial basin screening to final decisions with greater speed and confidence.
